In 1851, 500 Mormon settlers in 150 wagons arrived at the foot of the "arrow-marked mountain" seen in a vision of Brigham Young, and established the city of San Bernardino before continuing west to the Pacific. Some years later, David Noble Smith, a young pioneer in search of the perfect therapeutic waters around which to create his dream of a "hot springs infirmary," built the first known structures on the site and opened them to the public. Since that first sanitarium, three hotels with spas have been constructed at Arrowhead Springs over the years. Each reflected its era in style and function.
